Abstract
1. Arrangement for the optical measurement of the concentration of particles, comprising a light measuring means with at least one light source, a monochromator, a light sensor and indicator means and at least one space (B) which is enclosed by a membrane permeable by the particles to be measured (SSTi), the space (B) containing a substance and an indicator substance (IND) reacting to the concentration of the particles to be measured by a change in fluorescence, characterized by the choice of the substance such that the square of the solubility coefficients A1, B1 of the measuring object (A) and the substances enclosed in the membrane in space (B) are about inversely proportional to their coefficients of diffusion Ad, Bd.
